31). 40). Depending on Qf , Ki,if may be nonsingular (positive definite) or singular (positive semidefinite). This property will be important for stability and the inversion of the matrix Ki,if in coming sections. 43) is given in the following theorem. 2. 50) r with boundary condition wif ,if = xrT if Qf xif . Proof. 1. Thus, we derive the optimal cost using dynamic programming, where the optimal control and the optimal cost are obtained simultaneously. Let J ∗ (xi+1 ) denote the optimal cost associated with the initial state xi+1 and the interval [i + 1, if ].

116) where α is 1 when p ≤ q and 0 otherwise. Recall that the dimensions of inputs ui and outputs yi are p and q respectively. 117) Let a circle of radius Rf centered at (−1, 0) be C(−1, Rf ). e. 5 ≤ GM < ∞, and −π/3 ≤ P M ≤ π/3. 42 2 Optimal Controls on Finite and Infinite Horizons: A Review Fig. 5. 2 H∞ Control Based on Minimax Criterion In this subsection we derive an H∞ tracking control (HTC) for discrete timeinvariant systems in a state-feedback form. 120) where xi ∈ n denotes the state, wi ∈ l the disturbance, ui ∈ m the control input, and zˆi ∈ q+n the controlled variable which needs to be regulated.

62) Now, we have only to find the boundary value of gi,if and wi,if . J ∗ (xif ) should be equal to the performance criterion for the final state. Thus, wif ,if and gif ,if r r should be chosen as wif ,if = xrT if Qf xif and gif ,if = −Qf xif so that we have J ∗ (xif ) = xTif Kif ,if xif + 2xTif gif ,if + wif ,if r = xTif Qf xif − 2xTif Qf xrif + xrT if Qf xif = (xif − xrif )T Qf (xif − xrif ) This completes the proof. 2 will be utilized only for zero reference signals in subsequent sections. For positive definite Qf and nonsingular matrix A, we can have another −1 if the inverse of Ki,if exists.
